Der Erfindung stellt sich die Aufgabe, eine alternative wärmeisolierte Schlauchleitung bereitzustellen und ein Verfahren zu deren Herstellung.The invention has as its object to provide an alternative heat-insulated tubing and a method for their preparation.
Beschreibung der ErfindungDescription of the invention
Die Erfindung löst die Aufgabe mit den Merkmalen der Ansprüche, insbesondere mittels einer druckstabilen Schlauchleitung mit einer Wärmeisolierungsschicht, die einen elastischen, wärmebeständigen Kunststoffschlauch, ein auf dem Kunststoffschlauch aufliegendes Armierungsgewebe, das bevorzugt unmittelbar auf dem Kunststoffschlauch aufliegt, und eine auf dem Armierungsgewebe unmittelbar aufliegende Isolierschicht, die mit dem Armierungsgewebe verbunden ist, sowie optional eine äußere Farbschicht aufweist oder daraus besteht.The invention solves the problem with the features of the claims, in particular by means of a pressure-resistant hose with a heat insulating layer comprising an elastic, heat-resistant plastic tube, a resting on the plastic hose reinforcing fabric, which preferably rests directly on the plastic tube, and an immediately on the Armierungsgewebe insulating layer , which is connected to the reinforcing fabric, and optionally has or consists of an outer color layer.
Optional kann eine Faserschicht, die z.B. gewebt oder bevorzugt geklöppelt ist, zwischen dem Kunststoffschlauch und dem Armierungsgewebe angeordnet sein. Eine solche Faserschicht kann von einer Kunststoffmasse durchdrungen oder beschichtet sein. Bevorzugt ist eine solche Faserschicht frei von einer durchdringenden oder beschichtenden Kunststoffmasse bzw. besteht aus Fasern.Optionally, a fibrous layer, e.g. woven or preferably bobbin lace, be arranged between the plastic tube and the reinforcing fabric. Such a fiber layer can be penetrated or coated by a plastic mass. Such a fibrous layer is preferably free from a penetrating or coating plastic mass or consists of fibers.
Die innere Schicht der Schlauchleitung wird vorzugsweise von dem Kunststoffschlauch gebildet, der die Leitung für das Medium, insbesondere Dampf, bildet und weist keine zusätzliche Materialschicht auf seiner Innenseite auf. Der Kunststoffschlauch besteht bevorzugt aus wärmebeständigem Kunststoff, z.B. aus Polytetrafluorethylen (PTFE), Polyester-Elastomer (H), Polyamid (N), Nylon-Copolymer (NC), Fluorethylenpropylen (FEP), Ethylen-Propylen-Dien (EPDM), Polyurethan (U), Spezial-Elastomer (HF und/oder PFX), thermoelastischer Gummi (TPE), Polytetrafluorethylen (PTFE), Perfluoralkoxy-Copolymer (PFA) oder einer Mischung daraus, jeweils ohne oder mit integriertem Armierungsgewebe.The inner layer of the tubing is preferably formed by the plastic tubing which forms the conduit for the medium, in particular steam, and has no additional layer of material on its inner side. The plastic tube is preferably made of heat-resistant plastic, e.g. made of polytetrafluoroethylene (PTFE), polyester elastomer (H), polyamide (N), nylon copolymer (NC), fluorinated ethylene propylene (FEP), ethylene propylene diene (EPDM), polyurethane (U), specialty elastomer (HF and or PFX), thermoelastic rubber (TPE), polytetrafluoroethylene (PTFE), perfluoroalkoxy copolymer (PFA) or a mixture thereof, each with or without integrated reinforcement fabric.
Die Schlauchleitung weist bevorzugt keine zusätzlichen Materialien zwischen dem Kunststoffschlauch, der optionalen Faserschicht, der Armierung und der Isolierschicht auf. Die Außenfläche der Isolierschicht kann mit einer Farbschicht überzogen sein. The tubing preferably has no additional materials between the plastic tubing, the optional fibrous layer, the reinforcement and the insulating layer. The outer surface of the insulating layer may be coated with a colored layer.
Die erfindungsgemäße Schlauchleitung zeichnet sich dadurch aus, dass die Kautschukmischung, die die Isolierschicht bildet, unmittelbar auf das Armierungsgewebe extrudiert ist, bzw. dass das Armierungsgewebe mit der Kautschukmischung mittels Extrusion umspritzt ist, um die Isolierschicht auszubilden. Auf diese Weise geht die Isolierschicht eine formschlüssige Verbindung mit dem Armierungsgewebe ein. Durch das Extrudieren kann die Kautschukmischung, die die Isolierschicht bildet, in Zwischenräume des Armierungsgewebes eindringen und eine ausreichend feste Verbindung mit diesem eingehen, z.B. ohne dass eine zusätzliche Kleberschicht zwischen dem Armierungsgewebe und der Isolierschicht angeordnet ist. Die Kautschukmischung, die die Isolierschicht bildet, wird nach dem Umspritzen des Armierungsgewebes vernetzt, z.B. ausgelöst durch Erwärmung von außen und/oder durch Erwärmung von innen durch Fördern eines warmen Fluids durch den Kunststoffschlauch oder durch Bestrahlung mit β- oder γ-Strahlung.The hose assembly according to the invention is characterized in that the rubber mixture forming the insulating layer is extruded directly onto the reinforcing fabric, or that the reinforcing fabric is extrusion-coated with the rubber mixture in order to form the insulating layer. In this way, the insulating layer enters into a positive connection with the reinforcing fabric. By extruding, the rubber compound forming the insulating layer can penetrate into interstices of the reinforcing fabric and make a sufficiently strong bond with it, e.g. without an additional adhesive layer between the reinforcing fabric and the insulating layer is arranged. The rubber composition forming the insulating layer is crosslinked after encapsulation of the reinforcing fabric, e.g. triggered by heating from the outside and / or by heating from the inside by conveying a warm fluid through the plastic tube or by irradiation with β or γ radiation.
Das Armierungsgewebe kann aus Kunststofffasern bestehen, bevorzugt aus Metalldrähten, insbesondere aus Edelstahldrähten, die um den Kunststoffschlauch gewickelt, bevorzugt geklöppelt sind.The reinforcing fabric may consist of plastic fibers, preferably of metal wires, in particular of stainless steel wires, which are wound around the plastic tube, preferably fluffed.
Die Isolierschicht besteht vorzugsweise aus einer vernetzten Kautschukmischung, die Poren enthält, vorzugsweise geschlossene Poren, die z.B. Hohlräume sind, bevorzugt Mikrokugeln, z.B. vorexpandierte Mikrokugeln wie die unter der Bezeichnung Expancel von Akzo Nobel NV, Holland, vertriebenen, Mikrokugeln aus Glas, Phenolharz, Kohlenstoff oder thermoplastischem Kunststoff, insbesondere mit einer Größe < 100 µm, bevorzugter < 50 µm oder < 10 µm. Alternativ können die Poren durch Zusetzen eines Treibmittels in die Kautschukmischung erzeugt werden.The insulating layer preferably consists of a crosslinked rubber mixture containing pores, preferably closed pores, which are for example cavities, preferably microspheres, for example pre-expanded microspheres such as the microspheres of glass, phenolic resin, carbon sold under the name Expancel by Akzo Nobel NV, Holland or thermoplastic material, in particular with a size <100 μm, more preferably <50 μm or <10 μm. Alternatively, the pores may be created by adding a blowing agent into the rubber composition.
Bevorzugt hat die Isolierschicht eine Wärmeleitfähigkeit von maximal 0,2, bevorzugter von maximal 0,1 W/(mK). Preferably, the insulating layer has a thermal conductivity of at most 0.2, more preferably at most 0.1 W / (mK).
Die Isolierschicht kann z.B. eine Dicke von 10 bis 30 mm, bevorzugt 15 bis 25 mm aufweisen.The insulating layer may e.g. have a thickness of 10 to 30 mm, preferably 15 to 25 mm.
Die erfindungsgemäße Schlauchleitung hat den Vorteil, dass sie einschließlich ihrer Isolierschicht flexibel ist und einen einfachen Aufbau hat, so dass sie durch kontinuierliches Umspritzen der Armierung, die den Kunststoffschlauch einfasst, hergestellt werden kann und z.B. durch Ablängen und Anbringen von Anschlußstücken an ihren Enden konfektioniert werden kann. Die Schlauchleitung ist durch die Isolierung hinreichend isoliert, um den Wärmeverlust signifikant zu verringern und um hohe Temperaturen auf ihrer Außenfläche zu verhindern, z.B. wenn die Schlauchleitung eine Isolierschicht von 15 bis 20 mm aufweist und mit gespanntem Dampf von 150°C beaufschlagt ist.The hose assembly according to the invention has the advantage that it is flexible including its insulating layer and has a simple structure so that it can be produced by continuous encapsulation of the reinforcement which encloses the plastic hose and e.g. can be assembled by cutting and attaching connectors at their ends. The tubing is sufficiently insulated by the insulation to significantly reduce heat loss and to prevent high temperatures on its outer surface, e.g. if the hose has an insulating layer of 15 to 20 mm and is subjected to tensioned steam of 150 ° C.

Das Herstellungsverfahren weist die Schritte auf oder besteht daraus:
Anordnen eines Armierungsgewebes um einen Kunststoffschlauch,
optional Anordnen einer Faserschicht zwischen dem Kunststoffschlauch und dem Armierungsgewebe,
Umspritzen des Armierungsgewebes mit einer vernetzbaren Kautschukmischung, die Poren enthält, z.B. vorexpandierte Mikrokugeln oder ein Treibmittel, und
Vernetzen der Kautschukmischung. Das Vernetzen kann durch Erwärmen oder mittels Strahlenvernetzung erfolgen, insbesondere mit β-Strahlung oder γ-Strahlung.The manufacturing process comprises or consists of the steps:
Arranging a reinforcing fabric around a plastic tube,
optionally arranging a fiber layer between the plastic tube and the reinforcing fabric,
Overmolding the reinforcing fabric with a crosslinkable rubber mixture containing pores, eg pre-expanded microspheres or a blowing agent, and
Crosslinking of the rubber mixture. The crosslinking can be carried out by heating or by radiation crosslinking, in particular with β radiation or γ radiation.
Es hat sich gezeigt, dass die vernetzte Isolierschicht eine glatte Oberfläche und ausreichende Abriebfestigkeit hat.It has been found that the crosslinked insulating layer has a smooth surface and sufficient abrasion resistance.
Die Schlauchleitung ist ausreichend flexibel und weist bevorzugt eine ausreichende Festigkeit insbesondere des Verbunds zwischen der Armierung und der Isolierschicht auf, um für die dynamische Belastung durch Biegen geeignet zu sein, die in sogenannten Energieketten auftritt. Daher kann die Schlauchleitung in Energieketten angeordnet sein, insbesondere in Energieketten, die an gegeneinander beweglichen Teilen angebracht sind. Energieketten sind z.B. aus aneinander angelenkten bzw. gegeneinander verschwenkbaren Elementen zusammengesetzt, die z.B. einen einseitig offenen oder umfänglich geschlossenen Kanal bilden, in dem die Schlauchleitung angeordnet sein kann. Bevorzugt weist die Energiekette einen minimalen Biegeradius von zumindest dem fünf-fachen Außendurchmesser der Schlauchleitung auf.The tubing is sufficiently flexible and preferably has sufficient strength, in particular of the bond between the reinforcement and the insulating layer, to be suitable for the dynamic load of bending that occurs in so-called energy chains. Therefore, the hose can be arranged in energy chains, in particular in energy chains, which are attached to mutually movable parts. Energy chains are e.g. composed of mutually hinged or mutually pivotable elements, e.g. form a one-sided open or circumferentially closed channel, in which the hose can be arranged. The energy chain preferably has a minimum bending radius of at least five times the outer diameter of the hose line.
Bevorzugt weist die Schlauchleitung an zumindest einem Ende, bevorzugt an jedem Ende ein Anschlußstück auf, z.B. mit einer gegenüber der Schlauchleitung drehbar angeordneten Mutter. Das Anschlußstück ist bevorzugt eine Preßfassung mit einem in den Kunststoffschlauch ragenden Rohrstück und einer Preßhülse, die auf dem Armierungsgewebe aufliegt. Die Preßhülse kann mittels einer Presse radial auf das Armierungsgewebe aufgepreßt werden. Dabei ist die Isolierschicht in dem Bereich, in dem die Preßhülse auf dem Armierungsgewebe aufliegt, grob entfernt. Ein Vorteil liegt darin, dass zur Befestigung einer Preßfassung die Isolierung nicht vollständig von dem Armierungsgewebe entfernt sein muss, um eine ausreichende Fixierung einer Preßhülse zu erzielen. Daher kann beim Verfahren zur Herstellung die Isolierschicht grob entfernt werden und anschließend eine Preßhülse über einen endständigen Bereich des Armierungsgewebes aufgeschoben und dann auf das Armierungsgewebe aufgepreßt werden, wobei noch Reste der Isolierung auf dem Armierungsgewebe haften. Solche Reste der Isolierung sind z.B. in Zwischenräumen des Armierungsgewebes angeordnet und weisen bevorzugt eine Schichtdicke von maximal 1 mm, bevorzugt maximal 0,5 mm auf. Es hat sich gezeigt, dass die Isolierung dadurch hinreichend entfernt werden kann, dass sie nach Einschneiden bis angrenzend an das Armierungsgewebe längs der Leitung, bevorzugt nach zusätzlichem umfänglichem Einschneiden, manuell von dem Armierungsgewebe abgezogen bzw. abgerissen werden kann, ohne dass eine anschließende Reinigung des Armierungsgewebes erforderlich wäre. Preferably, the hose line at at least one end, preferably at each end of a connecting piece, for example with a respect to the hose rotatably arranged nut. The fitting is preferably a press fitting with a projecting into the plastic tube pipe section and a compression sleeve which rests on the reinforcing fabric. The ferrule can be pressed radially onto the reinforcing fabric by means of a press. In this case, the insulating layer in the region in which the compression sleeve rests on the reinforcing fabric, roughly removed. One advantage is that the insulation does not have to be completely removed from the reinforcing fabric in order to secure a press fit in order to achieve sufficient fixation of a compression sleeve. Therefore, in the manufacturing process, the insulating layer can be coarsely removed, and then a ferrule can be slipped over a terminal portion of the reinforcing fabric and then pressed onto the reinforcing fabric while still adhering remnants of the insulation to the reinforcing fabric. Such residues of the insulation are arranged, for example, in the interstices of the reinforcing fabric and preferably have a layer thickness of not more than 1 mm, preferably not more than 0.5 mm. It has been found that the insulation can be sufficiently removed by cutting it to adjacent to the reinforcing fabric along the line, preferably after additional circumferential incision, can be manually pulled or demolished from the reinforcing fabric without requiring subsequent cleaning of the reinforcing fabric.
Bevorzugt weist die Schlauchleitung zwischen einer auf das Armierungsgewebe aufgepressten Preßhülse und der Isolierschicht einen Bereich von maximal 2 mm, bevorzugter maximal 1 mm auf, in dem die Isolierschicht entfernt ist und das Armierungsgewebe nur von anhaftenden Resten der Isolierschicht oder nicht von der Isolierschicht überdeckt ist. Bei der Herstellung kann dies z.B. dadurch erreicht werden, dass die Isolierung in einem endständigen Bereich von dem Armierungsgewebe entfernt wird, der sich um 3 mm, bevorzugt 2 mm mehr entlang der Längsachse erstreckt, als die Preßhülse vor dem Pressen in Richtung der Längsachse misst. Denn durch das Pressen längt sich die Preßhülse, so dass sich die Preßhülse bis auf einen kleineren Abstand an die Isolierschicht erstreckt.Preferably, the hose between a pressed onto the reinforcing fabric press sleeve and the insulating layer has a maximum of 2 mm, more preferably at most 1 mm, in which the insulating layer is removed and the reinforcing fabric is covered only by adhering residues of the insulating layer or not of the insulating layer. In the manufacture this may e.g. be achieved in that the insulation is removed in a terminal region of the reinforcing fabric, which extends by 3 mm, preferably 2 mm longer along the longitudinal axis, as the ferrule measures before pressing in the direction of the longitudinal axis. Because by pressing the pressing sleeve lengthens, so that the press sleeve extends to a smaller distance to the insulating layer.
Die Erfindung wird nun mit Bezug auf die Figuren näher erläutert, die schematisch inThe invention will now be explained in more detail with reference to the figures, which are shown schematically in FIG
Die Schlauchleitung kann z.B. aus einem Kunststoffschlauch bestehen, der einen Innendurchmesser von 10 bis 30 mm mit einer Wandstärke von 2 bis 4 mm aufweist und aus PTFE besteht, der von einem Armierungsgewebe aus Edelstahldraht umklöppelt ist, das mit einer Isolierschicht umspritzt ist. Optional kann der Kunststoffschlauch ein innenliegendes Verstärkungsgewebe enthalten, optional kann zwischen dem Kunststoffschlauch und dem Armierungsgewebe eine Faserschicht liegen, z.B. Glasfasergewebe.The tubing may e.g. consist of a plastic tube, which has an internal diameter of 10 to 30 mm with a wall thickness of 2 to 4 mm and consists of PTFE, which is embroidered by a reinforcement fabric made of stainless steel wire, which is encapsulated with an insulating layer. Optionally, the plastic tube may include an internal reinforcing fabric, optionally a fibrous layer may be interposed between the plastic tube and the reinforcing fabric, e.g. Fiberglass fabric.
